可控制器

由于在网上很难下载到EDA技术－窦衡的PPT，所以本人经过学习后做成word，供大家下载。只针对VHDL语言部分和所有的程序。-Because the Internet is difficult to download to EDA technology- Douheng of the PPT, so I made after learning after the word, for all to download. Only for part of the VHDL language and all the procedures.

直接序列扩频通信（主要包括BPSK调制和BPSK解调以及PN码的产生）(Direct sequence spread spectrum communication (including BPSK BPSK modulation and demodulation, and the PN code generation))

说明：  fpga程序，产生1pps脉冲信号，使用的verilog语言。(FPGA program generates 1 PPS pulse signal, using Verilog language.)

saa7113_配置.SAA7113视频解码系列芯片的一种，8位彩色配置(saa7113_ configuration. SAA7113 video decoder chips in an 8-bit color configuration)

用FPGA实现数字锁相环，开发环境为ISE(Using FPGA digital phase-locked loop, development environment for ISE)

用VHDL语言编写的LED显示器驱动电路的设计源程序-using VHDL prepared by the LED display driver circuit design source

Verilog实现 spi接口的FPGA实现 通过仿真，修改后即可应用-Verilog realize spi interface FPGA to achieve through the simulation, the application can be modified

用VHDL编写的4、7、40、64、84计数器，可将程序中的具体数字设成任意值。-Using VHDL written 4,7,40,64,84 counter, you can program specific figures set to any value.

这是个双端口双端口ram的定义，当然读者在此基础上还可以扩充(This is a dual-port dual-port ram definition, of course, on the basis of the readers can also be expanded)

基于FPGA DE0以及niosII的射频无线发送程序,采用spi接口操作无线模块nrf24l01(To spi interface operation wireless module nrf24l01 of FPGA DE0, as well niosII RF wireless transmitter program)
